摘　　要：合空载R型卷绕式移动变电站会产生数值相当大的励磁涌流,易造成移动变电站保护装置的误动作。针对这一问题,理论分析利用控制三相合闸时间来削弱励磁涌流更具有潜力。Switching on the moving transformer substation of the idling R coiling type, it can generate the quite big excitation to flow rapidly; it＇s easy to make the disoperation for the protective device of transformer substation. In view of this question, hy the theoretical analysis, it has the potential that the control of three - phase switching on time weakens the excitation flows.
